Ed,
Are you sure about this because I was led to believe that the LINUX LPAR
runs off it's own processors ?

One more question : If the LINUX Lpar is running at 110% busy, does
this LPAR take power away from the 2 physical engines ?
Yes, but only due to the fact that it's an LPAR not that it's running at
110%
busy. IBM has worked on the state space switching algorithms in uCode and
it's gotten better over the years but it's still overhead and still hard to
measure precisely without large expenditures in hardware and people.
Remember one large shop gave a user benchmark(late eighties) with and
without PR/SM and it was near 30% overhead on a 400J.
